LobeHub
The ultimate space for work and life — to find, build, and collaborate with agent teammates that grow with you.
Project mention: Show HN: AI Roundtable – Let 200 models debate your question | news.ycombinator.com | 2026-03-24You can set this up yourself with API keys to the corresponding providers and creating an Agent Group in https://github.com/lobehub/lobehub. Agent groups allow you to easily create a room of agents and have them discuss any of your topics. Easily make agents with types and skills, it even assists in drafting starting prompts and even team members depending what your query (and selected model) is.
You can self-host as well, but not via desktop app. Sever setup required.
Be careful of your token context, you can easily rack up costs if you leave Opus selected as the model and get lost in some rabbit hole of results.
Enjoy enjoy!

> You can apply tags to blocks, which make them a kind of thing (a project, an author, a quote, a thought)
FWIW, needing typed notes is what settled me on Trilium Notes after a foray into a bunch of alternatives, including Notion, Anytype, Obsidian, etc
I realized that efficient note taking and knowledge management generally means (to me) having "dimension lists" (collections of places, people, projects, ...) being referred to in topical notes/journals/events, generally organized as a hierarchy (but not always). Once you come to that realisation (and that your notes system is essentially a glorified RDBMS), you want a system that ensures that "notes of the same type remain as consistent as possible", which Trilium makes easy via Templates and/or Inheritance (attributes can be inherited in the OOP sense, or composed like traits), collections to represent, manage and edit large amounts of notes at once, and emacs-levels of scripting if that's your jam.

Project mention: OpenKnowledge – open-source alternative to Obsidian/Notion | news.ycombinator.com | 2026-06-25
- A dual-observer CRDT to keep the ProseMirror and markdown state in-sync.
The CRDT + git also power a collaborative experience that shows what Agents are doing in the markdown, have undo/redo, and version history. The “Share” and cloud-sync functionality are geared for team collaboration. They feel “no-code” but leverage git/GitHub under the hood, which also means data stays fully private.
In that spirit, we made OpenKnowledge open source for anybody who’s curious or who’d like to contribute. Repo: https://github.com/inkeep/open-knowledge.
We’re actively thinking about plugins/extensibility and what’s next. If you have suggestions or feedback, would love to hear it.

> "- It was easier to find a link to where you worked at than your repo (https://github.com/skaldlabs/skald?tab=readme-ov-file), you should have linked it visibly"
Genuinely curious, can I ask why this is relevant to point out? This seems like just a general blog post, about raising money for a startup and personal reflections on it. Why would a link to a github repo be an important part of that?
